KDUtils is a library which provides both helpers and wrappers around the C++ STL and a base for cross-platform applications, similar to QtCore.

Also check out KDBindings for an implementation of properties, signals, and slots. Used heavily in KDUtils.

The KDFoundation namespace provides an event loop, an EventReceiver abstract class, and an Object type which is an event receiver that can have a parent Object and any number of children.

On top of that, you get:

• Event
• FileDescriptorNotifier
• Timer
• EventQueue: a thread-safe stack of events
• Postman: a way of passing events down a series of receivers
• CoreApplication: a class that connects the EventQueue, Postman, and event loop.

KDGui provides a cross-platform windowing solution, built on top of the CoreApplication.

You get:

• Window
• Keyboard and mouse events
• GuiApplication

KDMqtt provides a cross-platform MQTT client solution, based on mosquitto.

You get a thin wrapper around libmosquitto that

• seamlessly integrates into KDFoundation's CoreAppliation
• comes with an API featuring properties and signals using KDBindings

For now, we don't support building mosquitto from source so you need to have it installed on your machine. Minimal recommended version is libmosquitto v2.0.0 (previous versions are lacking full TLS support).

You can find setup instructions and download links at: https://mosquitto.org/download/

You may also want to have a look at the CI configuration of this project to see which dependencies we use to build KDMqtt.

This namespace is the namesake of the entire library, and contains the STL wrappers and helpers.

You get:

• ByteArray
• Dir
• File
• ElapsedTimer
• Flags
• Url
• Logging factory helper

On Linux:

sudo apt install libxkbcommon-dev libxcb-xkb-dev libxkbcommon-x11-dev wayland-scanner++ wayland-protocols libwayland-dev libmosquitto-dev

For debug builds with code coverage:

sudo apt install gcovr

On Android:

All dependencies are supplied by the Android SDK (version 32 and above) and NDK (version 26.1.10909125 and above).

An example app can be built and run by opening the directory examples/gui_window/android in Android Studio.
